President Donald Trump signed an executive order late Thursday to end public funding for the National Public Radio and PBS to stop what he called “biased and partisan news coverage.”

The order directs companies to conduct public broadcasting (CPB) to "stop federal funding for NPR and PBS" to the extent permitted by law. The order could be challenged in court.

“When the CPB was established in 1967, the media landscape is now full of rich, diverse and innovative news options,” the executive order on Thursday night reads. “In this environment, government funding for news media is not only outdated and unnecessary, but also corrodes the emergence of news independence.”

Trump and his loyalists, including Elon Musk, have long complained about the bias and promotion of the left-wing incidents in NPR and PBS, accusation that has been strongly denied by executives of both organizations. Last month, Trump called on them to refund “Social Truth”, calling them “radical left ‘monsters’, which greatly hurt our country!”

To date, NPR and PBS have received approximately $5 billion in public funds, respectively, and earned money from sponsorship. NPR said less than 1% of the funds come from public information.

But Trump said in order that the CPB failed to follow the principles of fairness and impartiality of its public role.

"What perspective does NPR and PBS promote does not matter. Nothing matters," he said.

PBS and NPR did not immediately respond to NBC News' request for comment.

An NPR spokesman responded to a draft memorandum that outlined funding cuts in a statement last month.

PBS CEO and President Paula Kerger said last month that the order returned to the organization would "undermine the essential services provided by PBS and local member stations to the American people."

She added: “Nothing is more important than PB Americans, our work is only due to the bipartisan support we have been receiving from Congress.”

Earlier this week, three members of the CPB board were removed by email, leaving two left.

The three removed from office filed a lawsuit, but their attorneys were unable to express any irreparable harm that the CPB or the individual faced in court.

Therefore, the judge only ordered the Trump administration to provide 48 hours notice before replacing board members or interim members. Board members must be elected by the president and confirmed by the U.S. Senate.

The Commission on Protecting Journalists said in a report Wednesday that Trump's execution of orders during the first 100 days of his tenure created a "chilling effect and potentially reduce media freedom", including restricting access to regular journalists who follow the president and reopening the FCC investigation, including NBC News.

Former NPR editor Uri Berliner resigned last month and wrote an article aimed at criticizing the network's liberal stance and lack of political diversity. However, he stressed that he does not support refund NPR.

The Trump administration has repeatedly blocked journalists from covering news in the Oval Office and removed journalists from the Pentagon’s workspace, a series of critics who say critics have attacked independent news agencies’ efforts to report on his administration.
